ECM, to be or not to be?

I have an 84 k-5 blazer that came with a 305 ECM controlled engine. I swapped the old beast for a new GM 350 crate engine. Added edelbrock manifold (emission comp.) and an edelbrock 1400 carb, New Distributor. Now that I have removed all the emission controls I am stuck with the realization that I need to make a decision to use the ECM or NOT! I am currently running without it because the carb won't adapt, no egr, knock sensor broke off during engine swap, all the old emission equip was rotted to hell, and the distributor is not compatible. But what worries me most is the TCC (Transmission Converter Clutch) which engages the full torque converter for overdrive. I would like to bypass all the ECM stuff, use as much emission stuff as I can, and get the TCC to work with my transmission. Does anyone know if I can convert my electric solenoid controlled 700R-4 to vaccum or a switch?
